PURPOSE: The purpose of this study was to document, to our knowledge, the first reported case of keratoconus progression accompanied with newly diagnosed pellucid marginal degeneration after corneal cross-linking (CXL). METHODS: A novel case of further keratoconus progression plus development of pellucid marginal degeneration in the same eye after CXL was documented with supporting evidence from Scheimpflug and optical coherence tomography imaging. RESULTS: A male patient was diagnosed with progressive keratoconus in the left eye and treated with CXL when aged 25 years...

PURPOSE: The aim of this study was to report the first case of mycotic keratitis caused by Botryosphaeria dothidea. METHODS: A 29-year-old man developed a fungal infection after being hit with chestnut thorns in the left eye. In vivo confocal microscopy, microbial culture, and next-generation sequencing (NGS) were used in the diagnosis of mycotic keratitis. RESULTS: The patient was provisionally diagnosed with mycotic keratitis based on IVCM and promptly received local and systemic antifungal treatment with voriconazole and amphotericin B...

PURPOSE: The aims of this study were 1) to compare "front" and "rear" methods for loading Descemet membrane endothelial keratoplasty (DMEK) tissue into both micro-Jones and standard-Jones tubes and 2) to evaluate the efficacy of a cone-shaped glass funnel adapter designed to make loading DMEK tissue safer for corneal endothelial cells. METHODS: The corneal endothelium was stained with 0.06% trypan blue to confirm equivalence between mate corneas. The tissues were then processed using the Iowa Lions Eye Bank standard DMEK protocol...

PURPOSE: The aim of this study was to investigate the effects of chronic ultraviolet (UV) radiation exposure on the corneal microstructure using conjunctival UV autofluorescence (CUVAF) as a marker of exposure. METHODS: Young healthy adults aged 18 to 35 years were recruited. Participant's demographics and sun exposure behavior were recorded using questionnaires. Images of the bulbar conjunctiva from the right eye were captured and analyzed for the CUVAF area.

The ectatic disease of the cornea poses a significant challenge for ophthalmologists because commonly used treatments to improve visual acuity, such as spectacles and contact lenses, may not be effective, especially in advanced stages. In addition, the preferred surgical management, corneal transplantation, has various issues related to tissue availability, the steep learning curve, and postoperative complications such as tissue stability and half-life. Ongoing research for an alternative to keratoplasty has suggested various methods, such as corneal crosslinking, which can improve visual function when combined with other techniques...

INTRODUCTION: Keratoconus is an ectatic corneal disorder that causes low vision secondary to high myopia, irregular astigmatism, and loss of corneal transparency. In children, the disease behaves aggressively, progresses rapidly, is diagnosed at advanced stages, and presents an increased risk for corneal transplantation; however, only few studies in children have been conducted. PURPOSE: The aims of this study were to determine the frequency of keratoconus in patients younger than 18 years who underwent the Pentacam study because of high myopia or high astigmatism in the oblique axis, analyze topographic criteria and classify them into severity groups, and identify associated risk factors...

Antibiotic resistance has emerged as a critical threat for the treatment of bacterial ocular infections. To address the critical need for novel therapeutics, antibiotic drug repurposing holds significant promise. As such, examples of existing FDA-approved drugs currently under development for new applications, novel combinations, and improved delivery systems are discussed.

We report a unique case of fungal keratitis, caused by the Cladosporium species, which is found to be resistant to multiple drugs, including voriconazole. Cladosporium belongs to the dematiaceous group of fungus, which is present ubiquitous in air, water, food etc. There are only few case reports available about Cladosporium keratitis which shows the successful management with voriconaozle. But in our case, the Cladosporium species was found to be resistant to multiple drugs, including voriconazole, and was successfully managed by topical povidone iodine (PVI) 5%...
